-
Le mveliso inentsimbi ye-alloy ye-20Cr2Ni4A enamandla aphezulu, eyaziwa ngokuba namandla ayo agqwesileyo kunye neempawu zayo zokuqinisa. Ifanelekile kwiindawo ezinzima ezifana neegiya kunye neeshafti ezinyamezela uxinzelelo oluphezulu. Qaphela ukuba emva kokufaka i-carburizing, kufuneka kuphetshwe ukucima ngokuthe ngqo ukuze kuncitshiswe i-austenite egcinwe kumphezulu, ukuqinisekisa iziphumo ezifanelekileyo zonyango lobushushu. Ifumaneka ngobubanzi ukusuka kwi-φ2mm ukuya kwi-φ500mm ukuhlangabezana neemfuno ezahlukeneyo zoomatshini abachanekileyo.
1). Izinto: Intsimbi ye-alloy yoMgangatho oPhezulu ye-20Cr2Ni4A
2). Ubungakanani: Ububanzi φ2mm - φ500mm (Ubukhulu obulungiselelweyo buyafumaneka xa buceliwe)
3). Unyango Lomphezulu: Mnyama, Uqaqambile, Ukhazimlisiwe, okanye ngokweemfuno zomthengi
4). Ukupakisha: Ukupakisha okuqhelekileyo okufanelekileyo elwandle (okuhlanganiswe ngemicu yentsimbi, kusongelwe ephepheni elingangeni manzi, okanye ngokweemfuno zomthengi)
Ukususela kwiimvavanyo zokuqala ezincinci, ukuya kuluhlu olupheleleyo lwangoku lweemveliso zentsimbi ezijikelezayo ezigubungela ukusuka kwi-φ2mm ukuya kwi-φ500mm, iimeko zokusetyenziswa kwe-20Cr2Ni4A ziye zanda ngokuqhubekayo. Ezo zincinci (φ2 - φ50) zisetyenziswa kakhulu kwiigiya ezichanekileyo, ii-plunger zepompo yepetroli, njl.njl.; ezo ziphakathi nezinkulu (φ50 - φ500) zisetyenziswa kakhulu kwiigiya ze-drive axle zezithuthi ezinzima, ii-transmission shafts zoomatshini bokwakha abakhulu, kunye nezixhobo ezinganyangekiyo zezixhobo zemigodi. Iimpawu zayo ezibalaseleyo zokucima kunye nokupholisa ziqinisekisa ukuba iindawo eziphambili zezixhobo ezinkulu nazo zinokufikelela kwiziphumo ezilungileyo zokuqinisa.
1. Ukuqina okuphezulu: Umxholo ophezulu we-nickel-chromium unika le nto ukuqina okuphezulu, kwaye umongo weendawo ezinkulu nawo unokufezekisa isiphumo esihle sokuqinisa.
2. Ukuhambelana kwamandla aphezulu kunye nokuqina okuphezulu: Ukudibanisa amandla aphezulu kunye nokuqina okuphezulu, kulungele imithwalo yempembelelo kwiimeko zokusebenza ezinzima.
3. Amanqaku aPhambili eNkqubo: Emva konyango lwe-carburizing, ukucima ngokuthe ngqo akucebisi. Endaweni yoko, kufuneka kusetyenziswe ukucima kwakhona okanye unyango olubandayo kakhulu ukuze kuncitshiswe i-austenite eseleyo kumphezulu, ukuqinisekisa uzinzo olulinganayo kunye nobomi bokudinwa koqhagamshelwano.
4. Uluhlu lweenkcukacha: Singabonelela ngentsimbi ejikelezayo ekhutshiweyo ebanda ngobukhulu obupheleleyo ukusuka kwi-φ2mm ukuya kwi-φ500mm, ukuhlangabezana neemfuno zokucubungula ngokuchanekileyo.
I-20Cr2Ni4A, njengomgangatho ophezuluIbha ejikelezileyo yentsimbi ye-alloy, inamandla aphezulu, ukuqina okugqwesileyo, kunye nokuqina okubalaseleyo. Isetyenziswa kakhulu kwiimeko ezahlukeneyo zokuhambisa umthwalo onzima, impembelelo, kunye nokuchaneka. Ngoluhlu olubanzi lweenkcukacha oluvela kwi-φ2 ukuya kwi-φ500, ayinakuhlangabezana neemfuno zokucubungula iindawo ezincinci kuphela kodwa ikwanakho nokuhlangabezana neemfuno zokuthwala umthwalo wezinto ezinkulu zesakhiwo.
I. Inkqubo yoThumelo lweMishini enzima
Izinto ezisetyenziswayo: Iigiya ezinzima, iigiya zeegiya, iigiya ze-drive axle, iishafts ze-spline, iishafts ze-transmission cross
Inkcazo yesimo: Kwiimashini zemigodi, kwiimashini zokwakha nakwiilori ezinzima, izinto zothumelo kufuneka zimelane ne-torque ephezulu kakhulu kunye nemithwalo yempembelelo. Emva kokufaka i-carburizing, umaleko womphezulu we-20Cr2Ni4A ufumana ubunzima obukhulu, ngelixa umbindi ugcina ubunzima obuphezulu, obunokumelana ngempumelelo nokuguguleka komphezulu wamazinyo kunye nokuqhekeka kweengcambu zamazinyo, nto leyo eyandisa kakhulu ubomi benkonzo yesixhobo.
